Turkey to link credit card limits to income

The policy matters because credit card limits are not just a consumer issue; they are a transmission channel for household spending, delinquency risk and broader financial stability. In a high-inflation economy, elevated card limits can temporarily support consumption, but they also raise the risk that families borrow beyond their repayment capacity, especially when borrowing costs are high and wage growth can lag living costs.

Turkey already has formal income-to-limit rules, but the new plan would make those rules harder to sidestep by improving the underlying data banks use. Current regulations cap a customer’s total card limit at twice average monthly income in the first year and four times income thereafter. The BDDK also decided in January 2026 that income must be verified with documents that can be substantiated when a new card is issued or a limit is raised.

The shift suggests the government wants fewer automatic or loosely justified limit increases and more scrutiny of actual repayment capacity. That could slow growth in unsecured consumer credit, but it may also reduce future losses for banks by preventing customers from reaching limit levels far above their earnings.

Officials say the aim is to reduce over-borrowing and support financial stability, and the emphasis on data integration indicates enforcement will matter as much as the rule itself. Linking payroll and social security data with the Risk Center could give lenders a fuller view of indebtedness, making it harder for multiple banks to extend overlapping credit to the same borrower.

For investors, the immediate question is how aggressively banks will have to adjust existing portfolios. The government has not yet said whether already-issued high-limit cards will be cut back automatically, and the details will shape the earnings impact for lenders with large credit card books. Any forced normalization of limits could pressure revolving balances and fee income in the near term, but it would likely improve asset quality over time.

The timing also matters for the wider credit cycle. Authorities are simultaneously trying to ease financing for larger projects and support mortgage lending, which shows they are not broadly anti-credit. Instead, they appear to be narrowing consumer risk while preserving institutional lending capacity. That split approach points to a policy mix designed to contain household leverage without choking off investment.

Banks, card users and investors will now be watching the implementing regulations for one key answer: whether the new framework mainly tightens future lending or also triggers a broader reset of existing limits across Turkey’s 40.7 million credit card users.
